Application filed November The principal objects of the present invention are to provide an extremely simple and therefore comparatively inexpensive track or guide rail construction; to provide for utilizing the weight of the track construction in heavy single guide rails rather than in flimsy7 multiple tracks; to employ simple and positively acting means for dumping the bucket; and to provide a bale construction adapted to support and guide the bucket on two side rails, to permit the bucket to invert to discharge while supported by the bale and the rails, to retain the relative position of bucket and bale in such a way that the rails cannot only beI vertical but also inclined, and to provide for guiding or supporting the bale at the top of the lift while the bucket is inverted.

Other objects of the invention will appear from the following description at the end of which the invention will be claimed and in connection with which reference will be made to the accompanying drawing forming part hereof and in which Figure 1 is a side elevational View of a skip hoist embodying features of the invention and illustrating two positions of the bale and bucket.

Fig. 2 is a front View of one-half of the structure shown at the upper portion of Fig. 1.

Fig. 3 is a transverse sectional view drawn to an enlarged scale and taken on the line 3-3 of Fig. 1 looking upward, and

Fig. 4 is a similar view taken on the line 4 4 of Fig.,1. I

Referring to the drawing and in the following description reference will be made in some cases to one side of the structure because the other side may be a duplicate of it. There are two single guide rails 1, each shown to consist of a flanged section, Figs. 3 and 4. These single guide rails 1 are provided with confronting marginal notches 2, Figs. 2 and 3, affording or providing full width roller runways 3, Figs. 2 and 4, and narrow width runways 4, Figs. 2 and 3. The bale 5, has rollers 6 adapted to run on the full width rollerrunway 3 and arranged in four pairs disposed near the ends of the bale and of which two 'pairs are adapted to receive one of the guide rails 1 between them and of lwhich two pairs are adapted toreceive the other of the guide 0F PHILADEL- SKIP HOIST.

rails between them. 7 are discharge rails projecting from the guide rails in proximity with the notches 2 and they are aligned substantially with the notches. As shown in Fig. 3 the discharge rails 7 through the intervention of fittings 8 are attached to the flanges of the guide rails 1. The bucket 9 is pivoted near one of its lower corners to the bale 5, and it is provided near its free edge with two pairs of rollers 10 and 11, of which one roller, 10, in each pair is arranged to run on a narrow runway 4, and to pass through a notch'2, and of which the other roller 11, is adapted to run on the full width roller runway 3 and on the discharge rail 7 As shown the roller 11 is wider than the roller 10. 12 is a safety hook carried by the bucket and adapted to engage the bale. The pivotal connection between the bucket and the bale includes the slot 13 in the bale and a through shaft 14 on the bucket, thus providing a rope take-up device when the bucket is in the pit. The bale is olset as at 15 to provide clearance for the rollers on the bucket. y

In operation the rollers on the bale in all normal positions of the bucket remain in engagement with the guide rails 1. During lift the rollers V10 and 11 on the bucket near its free edge engage and remain in engagement with the rails 1, the roller 11 traveling on the full width roller runwayl and the roller 10 traveling on the narrow width roller runway. This is shown in dotted lines in Fig. 1. In dumping position, as shown in full lines in Fig. 1, the narrow rollers 10 pass through the notches 2, and the wider rollers 11 leave contact with the guide rails 1 and ride on the discharge guide rails 7, thus the bucket is inverted and the page is properly supported at the top ofthe It will be obvious to art to which the invention relates that modiications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited-as to those matters or otherwise than the prior art and the appended claims may require.

We claim:

1. A skip hoist comprisin two single guide rails provided with con renting marthose skilled in the ginal notches, discharge rails angularly disposed with respect to the guide rails, a bale having rollers adapted to continuously engage and run on the faces of said guide rails, and a bucket pivoted to the bale and having rollers adapted to run on one of the outer faces of said guide rails and on the discharge rails and having rollers adapted to run on the other of the outer faces of the guide rails and to pass through said notches.

2. A skip hoist comprising two single guide rails each consisting of flanged sections provided with confronting marginal notches, discharge rails angularly disposed with respect to the guide rails and carried by the flanges of the sections of the guide rails, a bale having rollers adapted to continuously engage and run on the faces of said guide rails, and a bucket pivoted to the bale and having rollers adapted to run on one of the outer faces of said guide rails and on the discharge rails and having rollers adapted to run on the other of the outer faces of the guide rails and to pass through said notches.

3. A skip hoist comprising two single guide rails provided with confronting marginal notches, discharge rails angularly disposed with respect to t-he guide rails, a bale having rollers adapted to continuously engage and run on the faces of said guide rails, and a bucket pivoted to the bale and having rollers adapted to run on one of the outer faces of said guide rails and on the discharge rails and having rollers adapted to run on the other of the outer faces of the guide rails and to pass through said notches, said bale being olfset to provide-clearance for the bucket rollers.

4. A skip hoist comprising two single guide rails provided with confronting marginal notches, discharge rails angularly disposed with respect to the guide rails, a bale having rollers adapted to continuously engage and run on the faces of said guide rails, a bucket pivoted to the bale and having rollers adapted to run on one of the outer faces of said guide rails and on the discharge rails and having rollers adapted to run on the other of the outer faces of the guide rails and to pass through said notches, and a safety hook carried by the bucket and adapted to engage the bale.

5. A skip hoist comprisin two single guide rails provided with conronting marginal notches, discharge rails angularly disposed with respect to the guide rails, a bale having rollers adapted to continuously engage and run on the faces of said guide rails, and a bucket pivoted to the bale and having rollers adapted to run on one of the outer faces of said guide rails and on the discharge rails and having rollers adapted to run on the other of the outer faces of the guide rails and to pass through said notches, the ivot between the bale and bucket including a slot and pin connection.

6. A skip hoist comprising two single guide rails provided with confronting marginal notches affording full and narrow width roller runways, a. bale having rollers adapted. to run on the full width roller runway and arranged in four pairs disposed near the ends of the bale and of which two pairs are adapted to receive one of the guide rails between them and of which two pairs are adapted to receive the other of the guide rails between them, discharge rails projecting from the guide rails in proximity with the notches and substantially aligned therewith, and a bucket pivoted near one of its lower corners to the bale and having near its free edge two pairs of rollers of which one roller in each pair is arranged to run on a narrow width runway and to pass through a notch and of which the other roller is adapted to run on a full width roller runway and on the discharge rail.
